FIRE EXTINGUISHER OF THE LIQUID TYPE.

for naval purposes, or the like, has been dis-- continued.

My invention relates to a fire extinguisher of the liquid type wherein the aforesaid defeet is obviated i. e. the phosgen is entirely I am. further enabled to form a fireproof la'yer'at the place upon which the contents of the extinguisher are directed, thus preventing the fire from breaking out again at that point when the extinulshing li uid is volatilized, this latter effect being a 0 made rapid.

In a general manner, I add to the usual extinguishing liquid itself, such as tetrachloride of' carbon, trichlorethylene, tetrachlorethane or the like, a suitable amount of a substance or a mixture of substances, in-

dicated as follows:

1. Fatty substances. 2. Hydrocarbons of the aromatic series.

3. Sulphochloride of thiocarbonyL.

] 4. Tetrachlorosplphide of carbon.

1. -Among the fatty substances, I may employ for instance the fatty acids, animal or'vegetable grease, animal or vegetable oil (sulphonated or not), or the sulpho-ricinates,

as well as their solutions, mixtures, or combinations, and such substances will also lubricate the .frictional parts of the. apparatus, while at the same time exercising a physical action consisting in the formation of a sort of coating upon the burning bodies whereby the extinguishing liquid is maintained-in contact with the same.

2.As to the hydrocarbons of the aromatic series, I may employ the benzenic carbides and their derivatives, the pyrogenated hyalrocarbons (naphthalene anthracene, etc.)

and their derivatives; a so their solutions, mixtures or combmat1ons',;wh1ch W111 further act as absorbents for toxic gas or vapours.

3.Sulphochloride of thiocarbonyl. I may em lo its solutions mixtures or combina tions.

4.Tetrachlorosulphide "of carbon (with traces of iodine or not) The solutions, mix-' tures or combinations of this body maybe used. v

For the composition of an extinguishing liquid according to my invention, the fol lowing substances aregiven by way of ex- R0 Drawing. Application filed November 6, 1925, Serial No. 67,446, and in France November 10, 1924.

ample, but the proportions are not of a limitative nature:

. Kga. Tetrachloride of carbon 160 Sulpho-ricinate of sodium 1 to 2 Naphthalene '1 to 25 they will not form deposits which clog up the apparatus and hinder its operation.

It should be observed that among the aforesaid bodies which are mixed with the extinguishing liquid itself, certain of these --will only perform their functions after having remained for a sufiicient time in contact with the extinguishing liquid.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be per formed, I declare that what I claim is:

1. A fire extinguishing liquid which will not form phosgene at the time of its projection, cons sting essentiall of an extinguishing liquid in mixture wit 1 a fatty substance.

' 2. A fire extinguishing liquid. which will not form phosgene at the time of its projection, consisting essentially of an extinguishing liquid, 'a fatty substance, anda polynuclear aromatic hydrocarbon. 3. A fire extinguishing liquid which will not form phosgene at the time of its projection, consisting essentially of carbon tetrachloride, sodium sulpho-ricinate, and naphthalene. a I

, 4.. A fire extinguishing liquid which will not form'phosgene at the time of its projection, consisting essentially of 160 parts of carbon tetrachloride, 1 to 2 parts of sodium sulpho-ricinate, and 1 to 25 parts of naph-' thalene.

In testimony whereof I afiix my signature.
